I have a LG FLATRON W2253VP widescreen monitor. No matter how I run X,
the monitor goes blank, enters power saving mode, and I must reboot to
reactivate the monitor.
The computer has not crashed - I can ssh to the machine. I can tell
from a ps that the X process is still running, and also that the
keyboard is active, because I can exit the server using ctrl-c or
ctrl-alt-del.
But nothing I do brings anything back to the monitor screen, including
trying to switch to another virtual terminal.
What I have tried:
startx
Xorg -configure and then
Xorg -config xorg.conf.new
Xorg -config xorg.conf.new -retro
Then I tried developing my own modeline from the Xlog file. This is
what I ended up with, and placed in a my.xorg.conf file:
Section "Monitor"
#DisplaySize 490 320 # mm
Identifier "Monitor0"
VendorName "LG (GSM)"
ModelName "W2253"
# HorizSync 30.0 - 83.0
# VertRefresh 56.0 - 75.0
ModeLine "1920x1080" 138.5 1920 1968 2000 2080 1080 1083 1088 1111
# Option "DPMS"
EndSection
Xorg -config my.xorg.conf
Xorg -config my.xorg.conf -retro
Same result. Monitor in power savings mode and a reboot each time.
I wrote to the Freebsd list for help. Suggestions there:
1. disable HALD and DBUS.
I tried this, using startx and Xorg -config etc. Same result.
2. try using XDM.
Same result.
I also tried a new Screen section:
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1920x1080"
EndSubSection
EndSection
It didn't work.
I've googled and googled, but haven't found anything. qIf anyone could help me
out, I would be so grateful.
Thanks,
Scott
If you look at that Xorg log, you'll see that the EDID received for the monitor
doesn't show 1920x1080 as a valid resolution. Have you tried running with a very
simple xorg.conf like:
Section "Device"
Identifier "dev0"
Driver "radeon"
EndSection
From there you can use xrandr to play around and add modelines. I can't
remember it off the top of my head, but there's a nice little utility that
generates modelines for you.
